Maintenance and service
Replace battery modules
This UPS has easy-to-replace, hot-swappable battery modules. Replacement is a safe procedure, isolated
from electrical hazards. You may leave the UPS and connected equipment on during the replacement
procedure.
Once the batteries are disconnected the connected equipment is not protected from power outages.
Refer to the appropriate replacement battery user manual for battery module installation instructions. See
your dealer or contact APC at www.apc.com for information on replacement battery modules.
Service
If the unit requires service do not return it to the dealer. Follow these steps:
1. Review problems discussed in “Troubleshooting display messages” on page 26 to eliminate
common problems.
2. If the problem persists, contact APC Customer Support through the
APC Web site, www.apc.com.
– Note the model number of the unit, the serial number located on the back of the unit, and the
date purchased. If you call APC Customer Support, a technician will ask you to describe the
problem and attempt to solve it over the phone. If this is not possible, the technician will issue
a Returned Material Authorization Number (RMA#).
– If the unit is under warranty, repairs are free.
– Procedures for servicing or returning products may vary internationally. Refer to the APC Web
site for country specific instructions.
3. Pack the unit in its original packaging. If this is not available:
– Pack the unit carefully to avoid damage in transit. Never use Styrofoam beads for packaging.
– Damage sustained in transit is not covered under warranty.
4. Always DISCONNECT THE UPS BATTERY before shipping in compliance with U.S.
Department of Transportation (DOT) and IATA regulations. The battery(s) may remain in the
unit.
5. Mark the RMA# on the outside of the package.
